中文摘要：

设计了一种新型差动自感式磁流变阻尼器（DSMRD），研究中发现该阻尼器中的绕线缸体在磁场中容易产生漏磁现象。基于此现象，建立了不同绕线缸体材料的DSMRD磁场仿真模型，对绕线缸体构成材料与漏磁之间的关系进行了仿真分析。仿真结果表明：导磁缸体较不导磁缸体具有更好的磁场吸附能力，且能产生更高的感应电动势；采用铝和不锈钢这两种不导磁材料制成的绕线缸体产生的磁场强度接近，并且产生的感应电动势也基本相同。因此可通过改变绕线缸体材料来达到优化DSMRD的自感磁场和阻尼磁场的目的。

英文摘要：

In order to avoid the magnetic flux leakage of winding cylinder of DSMRD, the magnetic field simulation models under different winding cylinder materials were built up to investigate the relationships between the magnetic flux leakage and three winding cylinders made by different kinds of materials. The simulation results show that winding cylinder made by No. 10 steel material has stronger ability to reduce flux leakage than the winding cylinder made by aluminum and stainless steel materials, and the winding cylinders made by aluminum and stainless steel materi- als have nearly same magnetic field intensity and induced voltage. The simulation results can provide some guidance to optimize magnetic field by finding a suitable winding cylinder material.
